How to merg a Command module and a Mun lander

[Hoggorm]

Hi,

I have a command module and a Mun lander that I'd like to launch together. Unfortunately, I am not able to merge as intended and was wondering if anyone could help me. Please see attached images:

 

 

  

 

I am able to connect them if I place the lander on top of the command module, but that is not what I want. I would like to have the lander under the command module engine.

 

I've tried to use various decouplers on the engine for example the TR-2C Stack Separator. I can attach the decoupler to the engine on the command module, but the lander will not connect to it. I've also tried to attach a docking port to the TR-2C. It works, but again the lander will not attach to it.

 

Any suggestions on how I can fix this?

 

Thank you!

Hi there,

this should work:

-Build the LM first

-Select the "root" tool, and set the docking port on the top as a root part

-Save the LM as a subassembly

-Start building a new ship, build your CSM

-Then select your LM from subassemblies, and you should be able to attach your LM's docking port to the engine

 

You do not need to have another decoupler between the docking port and engine, and you can even enable staging on the docking port.

Hope this helps,

Typo, sorry :)

Thank you Michal,

 

I've not tried this yet since I'm not home just now, but I have one question:

You say I should attach the docking port on the tom part. As of now I have it on the Science Junior. Should I remove it from there, and reattach it as a root part? What is the tom part you mention?

A stupid typo, sorry about that  I meant the docking port on the top of your LM. I hope everything is clear now.
